According to the remote annotation method, a communication link can be established between the smart phone and the conference tablet, the annotation track input by the user on the mobile phone is transmitted, and annotation on the conference tablet is completed with a small data volume.
Fig. 1 is an embodiment of a remote annotation method of the present application, including:
101. establishing a communication link between the smart phone and the conference panel;
before annotating, the smart phone and the conference tablet need to be connected. According to different meeting scenes, in a smaller meeting room, the connection between the smart phone and the meeting panel can be realized by directly using the WLAN or Bluetooth function, so that the method is convenient and fast. Preferably, a WiFi hotspot may be established by the conference tablet for connection by the smartphone. Or the smart phone and the conference tablet are in the same local area network, and then the connection can be automatically established. In some large conference halls, due to the limitation of signal coverage, both the mobile phone and the conference tablet need to be connected to the internet, and then the connection between the mobile phone and the conference tablet is realized.
102. The smart phone receives touch operation input by a user in a target touch area;
and the user operates the touch screen of the mobile phone and inputs the annotation content in the designated target touch area. The target touch area may be the whole mobile phone screen, but preferably, an area slightly smaller than the area of the mobile phone screen is selected in the mobile phone screen for touch input according to the mobile phone preset application software, so that function keys related to the conference tablet, such as page turning, brush, color card, and the like, are placed in other areas.
Optionally, since the image of the tablet is not synchronously displayed on the mobile phone in the application, the target touch area may be only a pure color area, and the annotation content input by the user may be immediately displayed in the target touch area in another color different from the background color, so that the user may see the input content of the user at the same time during annotation. The target touch area may also be only a pure color area, and does not display the annotation handwriting input by the user, which is specifically determined by the setting of the corresponding software function on the mobile phone.
103. The smart phone generates coordinate information according to the touch operation;
the smart phone records the operation of the touch area when the user inputs the annotation content in the target touch area, and converts the operation into coordinate information. It can be understood that the target touch area of the smart phone may be smaller than the area of the conference tablet, so that the annotation handwriting input on the smart phone needs to be amplified according to a certain proportion, so as to be conveniently displayed on the conference tablet. The smart phone can acquire the resolution of the conference panel in advance, perform coordinate conversion according to the target touch area and the resolution of the conference panel, and then generate coordinate information.
104. The smart phone sends coordinate information corresponding to the touch operation to the conference tablet through the communication link;
the smart phone sends coordinate information corresponding to the touch operation to the conference tablet through the communication link in step 101, and the coordinate information records a coordinate change process corresponding to the annotation operation of the smart phone when the user is at his own location. It is understood that the coordinate information may be saved in the native resolution of the smart phone or mapped according to the resolution of the conference tablet.
105. And the conference flat plate synchronizes the movement track of the virtual cursor according to the coordinate information.
And the conference flat plate synchronizes the moving track of the virtual cursor on the screen of the conference flat plate according to the received coordinate information. The cursor is typically visible so that the annotator can observe in real time whether the location of his touch input annotation is correct.
Alternatively, since the screen size, resolution of the smartphone may be different from the conference tablet, the coordinate information needs to be converted. If the conversion process is located on the mobile phone, the mobile phone performs coordinate conversion according to the size and the resolution of the conference panel before sending the coordinate information. If the conversion process is located on the conference tablet, the conference tablet also needs to know the resolution and size of the target touch area of the mobile phone so as to perform coordinate transformation.
106. And the conference tablet generates annotation handwriting according to the moving track of the virtual cursor.
And the conference tablet carries out color rendering on the moving track of the virtual cursor in a display screen of the conference tablet, and generates annotation handwriting for the participants to read.
It should be noted that, the smart phone in the above embodiment may be configured such that multiple smart phones control the same conference tablet to annotate, at this time, the conference tablet may only allow one smart phone to control the virtual cursor to annotate at the same time, and may also generate more virtual cursors, so that multiple smart phones may annotate on the same conference tablet at the same time, thereby facilitating communication between participants.
In another embodiment of the present application, the annotation function of the smart phone to the conference tablet can be actively initiated by the phone. Referring to fig. 2, the embodiment includes:

Or the smart phone and the conference tablet are in the same local area network, and then the connection can be automatically established. In some large conference halls, due to the limitation of signal coverage, both the mobile phone and the conference tablet need to be connected to the internet, and then the connection between the mobile phone and the conference tablet is realized.
202. The smart phone sends an annotation request to the conference tablet;
the smart phone is pre-installed with an application program corresponding to the annotating function of the conference tablet, and sends an annotating request to the conference tablet through the application program, wherein the annotating request comprises identity identification information and permission information of the smart phone.
203. The conference tablet starts a remote annotation function according to the annotation request;
and the conference tablet decides whether to start the remote annotation function or not according to the annotation request. If the conference tablet can know from the annotation request that the smart phone has higher authority, the conference tablet can directly start the annotation function, so that the user of the smart phone can conveniently annotate. If the identity of the sender of the annotation request is unknown or the authority is insufficient, the smart phone is allowed to annotate the conference tablet only after the confirmation of the operator of the conference tablet.
204. The smart phone receives touch operation input by a user in a target touch area;
205. the smart phone generates coordinate information according to the touch operation;
